[PATCH v8 4/9] dt-bindings: gpio: change items restriction of clock for rockchip,gpio-bank
From: Jianqun Xu
Date: Sun Aug 15 2021 - 21:20:12 EST
In the past we only need on clock which name "pclk" for a gpio controller.
In the new version gpio controller, there add some register to change
debounce clock dynamic, so the dt node needs to add the second clock, we
call it "dbclk".
The clock property need 2 items on some rockchip chips such as RK3568
SoCs.
